SIP
By default, Lifesize systems support the SIP protocol for placing and receiving video and voice calls. Lifesize Icon systems have the ability to register to two independent SIP services simultaneously, allowing registration to both a SIP video service and a local SIP VoIP telephone system. Configure SIP preferences in Preferences > SIP Registrar 1 (or 2).
NOTE: If UVC ClearSea manages your Lifesize Icon or your Icon is connected to the Lifesize cloud-based service, you cannot edit SIP Registrar 1 preferences. Instead you can use the SIP Registrar 2 preferences for registration with a local SIP voice service.
